The discovery in 1953 of the double helix, the twisted-ladder structure of deoxyribonucleic acid (DNA), by James Watson and Francis Crick marked a milestone in the history of science and gave rise to modern molecular biology, which is largely concerned with understanding how genes control the chemical processes within cells.
Mar 10, 2014 · The Double Helix. James D. Watson. 3.85. 18,971 ratings1,119 reviews. By identifying the structure of DNA, the molecule of life, Francis Crick and James Watson revolutionized biochemistry & won themselves a Nobel Prize. At the time, Watson was only 24, a young scientist hungry to make his mark.
DNA is a double helix; 2 strands, each one has coding areas ( which are 2% and maybe less) and non-coding areas . Within the gene itself there are non-coding sequences which their name is “ introns “. The non-coding area (outside the gene) of DNA strand has different types of sequences ; satellites and repeated sequencing . Is that true for ...

In molecular biology, the term double helix refers to the structure formed by double-stranded molecules of nucleic acids such as DNA. The double helical structure of a nucleic acid complex arises as a consequence of its secondary structure , and is a fundamental component in determining its tertiary structure .
